Problems solved by technology

[0009] Therefore, even if the quantum dot display panel is displayed in a dark state, the ambient light excites the red quantum dots 121 and the green quantum dots 122 to emit light, which reduces the display contrast of the quantum dot display panel and affects the user's viewing experience

Abstract

The invention provides a quantum dot display panel. The quantum dot display panel comprises a pixel layer, a lens layer and a brightness enhancement film, wherein the pixel layer comprises a pluralityof retaining walls and a plurality of sub-pixels defined among the retaining walls, and two sub-pixels of every three sub-pixels are filled with red quantum dots and green quantum dots; the lens layer is arranged on the pixel layer and comprises a lens array composed of a plurality of convex lenses, and the focus of each lens is located in the corresponding retaining wall; the brightness enhancement film is arranged on the lens layer and comprises a prism array composed of a plurality of prisms facing the pixel layer. When the ambient light enters the quantum dot display panel, the ambient light is converged and collimated through the brightness enhancement film; and then the ambient light is converged to a plurality of retaining walls with light absorption characteristics by the lens array. The lens array maintains the contrast of the quantum dot display panel; the brightness enhancement film enhances the wide-viewing-angle display effect of the quantum dot display panel.

Description

technical field [0001] The invention relates to the technical field of quantum dot display panels, in particular to a brightness enhancement film and a lens array for a quantum dot display panel. Background technique [0002] Quantum dots (quantum dot, QD) are tiny semiconductor particles at the nanometer scale, whose optical and electronic properties are different from larger general particles due to quantum mechanics. When the quantum dots receive external light, the electrons in the quantum dots will be excited, and the electrons will jump from the valence band to the conduction band. When the excited electrons return to the valence band again, they will release their energy with light emission. This is the so-called photo-emissive quantum dot. In addition, the quantum dots will also receive the energy provided by the electric field to generate light, which is the so-called electro-emissive quantum dots. [0003] The size of quantum dots affects their light-emitting pro...
